OIL BURNER.

Application med maren e, 192s. serial no. 623,836.

Be it known that I, JOSEPH HEINZEL, Va

citizen of the United States, residing at Grantwood, in the county of Bergen and State of New Jersey, have invented certain new and useful Improvements in Oil Burners, of which the following is a specication.

This invention relates to heaters, particularly to heaters which use oil or other volatile liquids as a fuel, the main object being to provide a device which may be used in conjunction -with any type of stove or furnace, and of such size as to be readily inserted and set up in said articles.

Another object is to provide an oil heater in which the surface of a burning pool of oil is atomized by jets of air and water vapor which may be used simultaneously or selectively as desired. A

These and other objects will become apparent in the description below, in which characters of reference refer tov like-named parts in the drawing.

Referring briefly to the drawing, Figure 1 is an elevational view showing'the method of applying the Jheater, said heater bein A shown partly in section.

Figure 2 is a top plan view of vthe body .of the heater, showing the disposition of the air and water vapor jets.

Fig-ure 3 is a sectional elevational view of the device taken on-line 3 3 of Figure 2,4 showing the method of anchoring the hood in place.

Referring in detail to the drawing, the numeral 10 indicates the annular wall of the heater body provided with a spherical bottom 11. A concentric funnel 12 having a tapered opening v13 thei'ein, rises vertically from the inner faceof opening 13 divergesand has its greatest dimension at the upper mouth of thev funnel. A semi-circular wall 14 is formed on opposite sides of the funnel and has a channel 1-5 which passes thru the bottom of the body member. A raised boss 16 is formed on the outer wall surface of the body and has the threaded end of a pi e line 17 secured therein. lSaid pipe line leads to an oil storage tank (not shown), whichv may be` situated at any convenient location. The main body is mounted on a plurality of spaced apart legs 18, the upper end of each leg having a ridge 19 formed thereon which isconcentric with the wall 10 but spaced apart therefrom by a channel 20. The latter receive he bottom 11. Thetemperature,

the annular wall 21 of an invertedl coneshaped hood 22 which has a-relatively large opening 23 at its upper end. The upper end of the hood wall is provided with a plurality of holes 24 thru which the air can freely circulate. A vaporizer head 25 having a semi spherical surface at its upper end and a substantially flat surface 26 at its lower side, is superposed above the opening 23. A

lug 27 at the lower edge of one side of the head has a pipe connected thereto which leads to a convenient water supply system.

`A similar lug 28 projects from the opposite side of vsaid head tangential ,with the top of the head and. receives one end of the pipe.

29. 'Said pipe passes substantially downwardly with a number of necessary bends, the opposite end 30 projecting into the funnel opening 13, said pipe end 30 being upturned. A chamber 32 is` formed `beneath the body of the device by a casing 31, said casing communicating with a motor driven blower 33 thru themedium of pipe 34.

In using the heater, the entire device is inserted into the' re box of a furnace or.

stove and may rest upon the grate thereof.

A pipe from a water supply 1s permanently secured in the lug 27, and a pipe 17 leading from a source of fuel oil supply is similarly tapped into the boss 17. Fuel oil 35 is allowed to flood the chamber '36 in the main body, its level being controlled by a suitable valve so that it will notoverflow in-to the air chambers 15. When the device is to be voperated* the surface of the oil is ignited and the flames therefrom will pass upwardly and contact with the underside v26 of the water head 25, the latter forming a baiiie lto said 'flame and thereby spreading the iiame and causing the same to traverse a greater area. The water within the head 25 is simultaneously vaporized and the steam .passes out of said head thru the lug 28 o and pipe 29. Said steam thence follows the course of the pipe to the top of its open opening 13 and expands over the chamber 36 directly above the liquid. Said steam, besides creating a strong draft, in mixing with the burning oil vapor aids atomization of the same and also gives the flame a higher which is desired. The flames after passin the water head 25 lead upwardly and the furnace, or any element which may be above the device.

end 30 whence 1t passes thru the tapered.

eat a water jacket as used in lin practice it has been found that so-me localities are not readily conducive to the use of steam as an atomizing medium, ow-

ing to the suspended deposits of lime and ot er matter which rapidly scale and clog the water supply pipe thereby, preventing lling of the water head. lin order to avoid this condition -the channels l are provided in the body of the device and form jets for the passage of air. Said jets communicate with the casing 32 which in turn is directly connected to a blower fan f-indi cated by the numeral 33. rllhe fanA when rotating causes a current of air to dow in the direction indicated by the arrow and passes upwardly thru the jets where it draws up and mixes with the burning oil .vapor in a similar manner to the steam above-described, and also aids atomization. rlFhe design of the device as shown in Figure l obviously permits both steam and air to be used simultaneously or selectively by independently operating either the air or water vapor systems. The device has been designed in the manner shown on the drawing with a view toward enabling the same to be readily dismantled when it is desired to-clean an of the parts, and also for its facility in s ipping and manufacture.

A device of the class described comprising a main hollo-w annular body, legs on said body, the upper end of said legs having ridges thereon, said ridges being separated from the wall of said body by a channel, a conical shaped hood adapted to be seated in said channel, said hood having a relativel large opening at its upper end, said mainf ody being adapted to receive fuel oil, a water head mounted above said hood, the dames of said oil being adapted to vaporize the water contents of said head, and means for conveying the water vapor to a position immediately above the surface of the oil.
